The present invention relates to a shoe in which air is circulated, and more particularly, to a shoe using an air circulation midsole having a well-ventilated air without providing a water circulation device in a shoe midsole in contact with a foot arch.

Shoes are generally classified into uppers, midsoles fitted inside the uppers, insoles in contact with the soles of the soles, and outsoles and heels attached to the lower portions of the uppers to touch the ground. .

Since such a foot is blocked by the components of the shoe, a lot of walking or wearing for a long time will release a lot of sweat from the sole of the foot.

As such, there have been many developments such as using a functional material such as cool fiber as an insole material to remove sweat or odor emitted from the sole of the foot, or providing an air circulation device that draws external air.

As a shoe provided with such an air circulation device, the air circulation shoe of the Republic of Korea Open Utility Model No. 1990-117 has been disclosed.

As shown in FIG. 1, the air circulation shoe is mounted on the heel portion of the shoe to introduce air.

The technology of this method has a limit on the life of the product due to the wear on the heel when the shoes are put on, and the life of the product is limited, and there is an air inlet on the heel on the ground, If present, water was introduced into the shoes with air.

As such, when water is introduced, water is introduced into the pump chamber for pumping air, and thus the water in the pump chamber is not quickly dried, and thus there is a drawback that it is not immediately available.

In addition, it is designed to be used only for the soles and soles that have thick front soles and flat to the heel, and the type of sneakers with mulberry on the soles such as men's shoes with separate bends, ladies' shoes such as high-heeled boots, and soccer shoes. There is a defect that can not be used in the installation of the prior art of this method was limited in the use that can be utilized.

In other words, the shoes we use in our daily life are different types of shoes are used for different purposes. For example, all kinds of sneakers such as soccer shoes, golf shoes, safety shoes used in industrial sites, rubber boots used in farming and fishing villages, men's or ladies shoes suited to formal wear, and casual shoes that can be worn comfortably. It is put to practical use depending on a use.

All of these shoes were used to protect the foot and use comfortably, but looking at the soccer shoes as one of the above types of shoes, there was no product designed to protect the ankle.

Since these shoes can not be made to ventilate smoothly due to radical movements, it is not possible to manufacture and use soccer shoes that can protect the ankles due to slippage due to the sweat of the feet. This is emerging.

The present invention was devised to solve the above problems, the purpose of the present invention is to install the air suction in the upper part of the upper to prevent the water from smearing, and to install the pleated tube between the upper and the inner skin to wear shoes It is to provide a shoe using the air circulation midsole that can prevent wear phenomenon by moving according to the movement of the shoe without bending because of the flexibility to move along the walk.
